Serial No. 432,968.

I' do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and usethe same. v

The invention to be hereinafter described relates to rossing or wood barking machines, and is particularly adapted for removing bark from pulpwood.

The object of the invention is to produce a simplified and im roved machine over that described in my Tnited States Patent No. 827,747.

Broadly speaking, the machine comprises a suitable framework, log feeding, log turning, knot cutting and log barking mechanism; means for rendering the log barking mechanism inoperative during the operation of the remaining mechanism, means for varying the operation. of the log feeding mechanism all said mechanisms and means being mounted on the framework.

In order to enable one skilled in the art to which the invention applies to the more readily understand the construction, operation and use of the machine, reference should be had to the accompanying drawings forming part of the present application, in which drawings like reference characters designate the same parts throughout the several views.

in the drawings: Figure l is a plan view of the machine, the log feeding mechanism being shown in section; Fig. 2 is a side elevation, showing the means for adjusting the tension of the yoke for rendering the rossing wheel inoperative; Fig. 3 is a vertical longitudinal section, showing the log feeding disks and their supports in section; Fig. 4 is a side elevation opposite to that shown in Fig. 2, and showing the levers for operating the f eed changing mechanism and the yoke operating mechanism; Fig. 5 is-a vertical longitudinal section through the log turning mechanism; Fig. '6 is a left-hand end View of Fig. 1; Fig. 7 is a cross section on line 7-7 of Fig. 1, looking in the direction of the arrow; Fig. 8 is a front view, of the rotarycutter head; Fig. 9 is a section on line -9-9 of Fig. 8, looking in the direction of thearrow, Fig. 10 is a section on line 1010 of Fig. 9; Fig. 11 is a section on line 111] of Fig. 12, looking in the direction of the arrow; Fig. 12 is a vertical longitudinal section, showing the connections between the pulley. and the shaft for driving the log feeding means; and, Fig. 13 is a section on line 13-13 of Fig. 8.

Any suitable solid form of framework may be used for supporting the various working parts of the machine. struction. however, it comprises a plurality of longitudinal beams placed substantially parallel with one another, and connected together by a number of strong lateral cross beams, which may be used for several purposesother than that of simple frame elements, all as will later appear.

Each of the cross beams may carry near one end an upright arm, onwhich is formed or mounted a tubular bearing 1, in which turns the main shaft 2 of the machine, to which are fixed the knot cutter 3 and rossm g wheel 4, each comprising substantially cylindrical heads provided with elongated openings through which cutting knives pro ect.

It will be noted that the knot cutter 3 and .rossing wheel 4 are each provided with flanges 0r circumferential ribs 3 and e respectively. These ribs serve to prevent logs from being too tightly pressed against the cutting knives. Such excessive pressure against the knives would result in shavingor.

cutting oil the wood'together with the bark.

On the outer faces of the bearingsl are mounted freely rotatable log turning wheels 5., each provided with oblique rows of ripping teeth, which engage and turn thel so that the knot cutter and rossing wheel may operate on all sides of them. The rim of each of these wheels is provided with perogs,

In the preferred conforations 6, which pass completely through the same and cooperate with the teeth of driving inions, thus providing means for driving t e wheels. The great advantage in having the openings 6 pass completely through the rim, is that the chips, dirt, bark, &c., cannot collect in the openings and clog them, as would otherwise. be the case.

To the forward end of the shaft 2 is fixed a rotary cutter head 7, carrying the cutter blades 8. About thecutter head is disposed a cylindrical guard 9, which revolves freely in an annular seat on the shaft 2, and is provided with openingsfi and oblique gripping teeth similar to those of the log turning wheels 5. This cutter is provided so that 4 them through the machine.

- stantia ly parallel with the shaft 2, a second the frame, and is driven from the first shaft I 13 carries a plurality of pinions 15, the teeth For this purpose, the wheel 5, just in advance rossing wheel 4. Should it be desired to past thcknives b For 0 crating the machine, fixed and loose pu leys 10 and 11 respectively are mounted on. the shaft 2 and driven by any suitable form'of belt or similar means. At the op osite side of the machine, and subshaft 12 is mounted in bearings carried by through suitable belt and pulley connections. From this second shaft 12, a countershaft 13, mounted in hangers 14 dropped from thelateral frame members, is driven by suitable sprocket and chain connection. The shaft of which cooperate with the o enings 6 in the rims of the walls 5 to drive t e same.

At times it is desirable to render the ros singwheel inoperative, while the other mechanisms are working. way to do this is to so mount one of the log turning wheels that it may be moved to guide the logs away from the rossing wheel.

of the rossing wheel, instead of being mounted on a stationary bearing similar to that of the other wheels, is mounted on a stub shaft or pintle 16, carried by a yoke 17, which is pivoted at 18 to an upright carried by one of the frame members. To the yoke 16 is fixed the lever arm 19, which is extended through the side ofthe framework and allowed a limited amount of play in a slotted bracket 20, being normally maintained in raised position by means of the adjustable. spring 21,. one end of which projects through a slotted guide in the bracket 20 and forms a seat for the lever end, while the opposite end is seated in a plate 22 adjustably secured to the machine frame. Thus, norniall thelever arni held raised, retracting the wheel 5 carried by the yoke and allowing the free working of the project the wheel carried by the yoke beyond the face of the rossing wheel 4 so that thelogs would be held away from the rossing wheel, the hand lever 23'will be thrown to the left, thus rocking the shaft 24, and, through the link connection 25, drawing down the lever arm-l9.

in order to feed the logs through the machine from the receiving to the deliveryend and 4, a plurality of adjustably inclined rotary serrated feed disks 26 are used, each disk having a vertical inclination as well as a variable inclination relative to the direction of feed of the lugs. Each of the disks is mounted to revolve freely about a of a post 23, W lich is revolubly mounted in lhe vertical bearing slccve'gfil carried inthe frame members. To the heads of the post The most practical pintlc 27 carried in. the head 28 are also secured, rigidly. arms 30. havin ball and socket connections 31'withs1eeves 32 on the shaft 12. Thus it will be seen that as the sleeves 32 are moved, the disks will be oscillated to change their inclinations relatively to the direction of feed of the lugs. Of course, as the inclination of the dis s varies or is changed, so will the rate of feed of the lugs vary or be changed.

On the arms 30 are revolubly mounted sleeves 33, provided withbeveled pinions 34 and 35, which mesh with beveled pinions 36 fixed to the shaft 12 and beveled gear teeth 37 on the rear faces of the disks. Ofcourse, the gear teeth are all of sufficient depth to maintain driving connections while the disks 26 are oscillated. between collars 38 fixed to the shaft 12, and

.the pinions 36 are also fixed thereto, and consequently must move longitudinally with the shaft, though the shaftis free to revolve withoutturning them.

It is obvious .that the driving connections between the shafts 2 and 12, and between the shaft 12 and countershaft 13, should not be altered by the longitudinal shifting of the shaft 12, as it is moved to change the feed'of the logs. To that end, the pulley and sprocket wheel respectively of such connections are made fast to a tube 39 revolubly mounted in hearings in posts 40 at he dolivery end of the machine, and the shaft 12 has one end inserted withinthe tugs and provided with an elongated slot 41, t rough which is passed the key 42, which fastensboth the tube 39, and pulley thereon, to the shaft 1.2, in such mariner that they are all forced to rotate together as a unit, altho'ilgh The sleeves 32 are held the shaft may be moved longitudinally in the tube for the full length of the slot- 41, Without moving either tube or pulley.

in order to shift the shaft; 12 as desired, a hand lever 43 is pivoted to thefranie adjacent to the delivery end of the same, and to this lever is connected one end of an arm44, the other end being connected to one of the sleeves 32. 'lhus when the-lever is swung to the left or right, the disks, through the connections previously mentioned, will beswung in the opposite direction.

-At the two opposite ends of the machine are placed idlers 45, similar in all respects to the disks 26, and having similar connections with the shaft 12, with the exceptioncf the' .driving gears, which, of course,- are omitted,

these idlers acting merely as additional supports and guides for the log.

The cutting or working arts ofthe m'aehinr are covered over by a fiood or guard 46,

which may be either rcmovably bolted to.

supports 47 forming part of the framework, or may be rigidly secured thereto. It is preferable, however, to have the hood rc' .inovably secured, so that it may be taken oil, and any accumulation of chips, bark, or

other debris cleaned away.

. parts of the machine: let, the driving con- 'named shaft, a pulley mounted on said a preferred form of the machine has been In the present application the improvements are chiefly confined to the following nections between the shafts 2 and 12, and 12 and 13 whereby the shaft 12 may be shifted longitudinally without shifting the pulley or sprocket wheel thereon, as shown in Figs. 11 and 12; 2nd, the particular forms of the gears or o enings 6 as shown in Figs. 5, 9 and 10; an 3rd, the cutter head, as shown in Figs. 1 5 and 9.

From the foregoing it will be noted that the gearing and more complicated parts of the mechanism are located at a distance from the barking and cutting mechanism, and thus are not likely to become clogged by chips or bark during the operation of the machine.-

It is clear that many changes may bemade in the construction of the several parts of the machine, that many rearrangements of these parts and many other combinations of them may be had, and that many substitutions for them may be made, without in any way de parting from the field and scope of the present invention, and it is meant to include all such within this application, wherein only shown and described.
